Former
"Bachelorette"Trista Sutter was on
"Good Morning America" Monday (Dec. 2) to promote her new book,
"Happily Ever After: The Life-Changing Power of a Grateful Heart," which stemmed from her daily reflections on faith that she does on Twitter.

"I tweet my #faith every day. It's just a way for me to reflect on the positive, the little things that have happened throughout the day, to end the day on a positive note and to know that the next day, I need to consciously be aware of the little things that happened," says Sutter.

"I think that gratitude is so important. I feel like when you're in the rough patches in your life, it has helped to lift me up, and when you're int eh high times, it helps to keep you grounded," she continues, adding that you have to be proactive about it -- she calls them "happily ever actions."

"My first chapter is called 'A Conscious Choice.' You need to actively choose gratitude and choose optimism in order to live a happy life," says Sutter.

When asked how she and Ryan managed to make it work -- when the "Bachelor" franchise shows do not have a great track record for marriages -- she says, "I think if you compare 'The Bachelor' and 'The Bachelorette' to the real world, it's not that different in that how many relationships do you go through before you find the one you want to spend the rest of your life with? But we just had all the components -- trust, honesty, respect, love, commitment, friendship, humor, all of things wrapped into one."
